RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No; 778,397, dated December27, 1904.

Application filed March 17,1904. Serial No. 198,531. i

To all whom it may concern:

Be it known that I, FRANK BAYLEYSS, a citizen of the United States,residing at Spring field, in the county of Clark and State of Ohio, haveinvented certain new and useful Improve ments in Railway-Switches, ofwhich the fol lowing is a specification.

My invention relates to improvements in railway-switches, and itparticularly relates to improvements upon the switch set forth in myPatent No. 7 50,334, issued January 26, 1904. r

The object of my invention is to provide means for looking or holdingthe movable rails into the position to which they have been moved by thetrain-operated devices of the switch, so as to prevent displacementthereof by a passing train after the rails have been thrown to closedposition by said train in the manner set forth in my said former patent.

A further object of my invention is to provide means to prevent therebound of the movable switch-point from the main rail which mightresult from the shock incidental to its operation, and, further, toprovide means to force the said switch-point back to its positionagainst the rail in case of any such re bounding or to force the pointup against the rail in the event the operating devices should notproperly do so.

My invention consists in the constructions and combinations of partshereinafter described, and set forth in the claims.

' In the accompanying drawings, Figure 1 is a perspective view of aswitch to which my invention has been applied. Fig. 2 is a bottom planView of my device, showing the parts in their operated position. Fig. '3is a device showing the parts in their normal position.

Fig. 4 is adetail showing the position of the parts after they have beenoperated. Fig. 5 is a detail showing in full linesthe device in apartly-operated position and in dotted lines the parts in normal andfully-operated positions, respectively. Fig. 6 is a detail of thestationary guide for the device, and Fig. 7 a view of one of the washersfor the spring. Fig. 8 is a bottom plan-view showing the parts in theirnormal or inoperative position.

Like parts are represented by similar letters 5 O are connected togetherby a bar a to which bar is attached the box or casing 0. Extendedthrough the casing and adapted to be normally connected thereto byspring-pressed plates 0 is the ordinary hand switch-bar 0, connected toa hand-switch 0 for the purpose of operating the switch-rails in theusual way. Also extended through the frame or casing 0 is atrain-operated bar 01, connected to train-operated devices 6 for thepurpose of operating said bar and in turn the switch-rails under certainconditions. This bar d is formed tapering at a point within the casingor frame 0, as shown at d so as when operated to contact with thespring-pressed'plates, and thus unlock the hand-operated switch-bar fromthe switchrails, and is also provided with a shoulder d near the pointwhere it passes through the frame or casing, which shoulder will contactwith the said frame or casing and move the same in the direction inwhich said bar 0? has been operated, so as to throw the switch-rails. InFig. 2 I have shown aspring d placed around the bar (2, between theshoulder and the side of the frame or casing, to obviate any undue jaron the parts at this point. The train-operated bar is adapted to beoperated by the said train-operated devices 6 in the manner described inmy said former patent, so that in the event of a train approaching aswitch I which has been left open suitable contacting devices may be seton said approaching train to operate the said train-operated bar toclose the switch.

In order that one of the switch-points or movable rails whenoperated'iby the train-operated devices shall be moved and firmly heldclose against the main rail to obviate any danger of disrailment, I haveprovided the following-described devices: Pivotally connected at (Z tothe train-operated bar (Z or to an extension (Z thereof, as shown in thedrawings, is an L- shaped arm f, one portion of which is provided withaslot f, through which is extended the upturned end f 2 of a stationaryguidefiwhich is secured to the under side of one of the ties. To theinner end of the slotted portion of the arm f is a collar f, and looseon said slot ted portion is a washer f adapted to fit against theupturned end of the stationary guide f Around the slotted portion of thearm f and between the collar and washer is placed a coil-spring f. Whenthe mechanism of the switch is in its normal condition, the parts of thelocking device are in the position shown in Fig. 3, with the springextended. When the train-operated bar (Z is operated by an approachingtrain to throw the switch-rails to their closed position, the movementof said bar will throw the devices to the position shown in Fig. 4,placing the spring under tension and causing it to exert an influence inthe direction in which said bar d has been moved, and thus, by reason ofthe connection of said bar with the movable or switch rails, through themedium of its shoulder and the casing or frame, as described, exerting apressure upon the said switch-rails tending to hold them in theiroperated position. As shown in Fig. 5, the point at which the spring isunder the greatest tension is when the parts have completed about halftheir movement. After the parts have been fully operated it will be seenthat before they can again be restored to normal position the springmust be placed under greater tension up to a certain point. Thus anytendency to jar the rails from their position will be resisted byincreasing tension of the spring. The parts can be restored to normalposition by pulling back the bar d by means of said train-operateddevices.

While I have described my invention as relating particularly to the formof switch set forth in my former patent, it is obvious that theinvention might be applied to a switch of somewhat differentconstruction, and I do not limit myself, therefore, in its applicationto the exact devices shown and described.

Having thus described my invention, I claim 1.
